    with highs in the 70s to low 80s.

  - Mostly dry conditions expected through the middle of next
    week.

  - Warming trend back to above normal temperatures early next
    week.

.SHORT TERM...
(This afternoon through Saturday)
Issued at 231 PM EDT Fri Sep 25 2026

A cooler airmass will continue to filter in over the CWA thanks
to a strong developing coastal low that will start to move along
the Eastern Seaboard over the short term. This developing system,
in combination with inland high pressure stationed over the Great
Lakes region, will support cool and dry conditions into the
weekend. As a result, expect dew point temperatures down into the
40s over the area on Saturday, continuing the `fall-like` feel in
the air. Daytime highs will top out in the mid to upper 70s today
and slightly warmer for Saturday afternoon. Overnight temperatures
will be crisp area-wide, dropping into the low to mid-50s on
Saturday morning at most locations. In addition to the cooler
conditions, expect skies to improve through the day Friday, with
partly cloudy to clear conditions expected this afternoon and
through tomorrow. Along with this dry pattern, there is no chance
of precipitation in the short term with tranquil conditions
expected.

.LONG TERM...
(Sunday morning through next Thursday)
Issued at 231 PM EDT Fri Sep 25 2026

The long term period will begin with a vertically stacked low
pressure system lingering near the New England Coast and a high
pressie mid-level ridge extending through the central CONUS. North
and central Georgia will be positioned underneath northwesterly
flow between these two features, which will continue to bring dry,
Canadian continental air into the region. This dry air, which
will limit dewpoints to the 40s and low 50s and precipitable water
values to 0.4-0.7 inches, combined with subsidence underneath
lingering surface high pressure will inhibit rain chances through
at least mid- week. On Monday and Tuesday, the low pressure system
will gradually weaken and move away to the northeast as the ridge
advances eastward. High temperatures on Sunday will be near to
just above climatological normals, in the mid 70s to low 80s in
north Georgia and low to mid 80s in central Georgia. Very dry air
will remain under the ridge, though the airmass will moderate and
temperatures will steadily climb each day. Low temperatures on
Monday and Tuesday will remain brisk and seasonable, in the upper
40s in far northeast Georgia and 50s elsewhere across the area. In
contrast, highs by Tuesday afternoon will be in the mid to upper
80s across the majority of north Georgia and low 90s in central
Georgia, which will be about 6-10 degrees above climatological
normals. With several days of dry weather and sunny skies, minimum
relative humidity values will need to be monitored on Monday and
Tuesday afternoons, as they could approach 25% in central Georgia
during peak heating each of those days.

On Wednesday, the axis of the ridge will move east of Georgia as
the associated surface high moves off the Carolina Coast. Moisture
will gradually begin to increase as the flow pattern shifts to
southwesterly. At this point, the tug-of-war between fall and
summer will be pulled back in the favor of "summer" as highs
remain in the mid 80s to low 90s and highs return to the 60s and
low 70s late in the week. A low pressure system moving through the
Great Plains will extend a cold front southward, which is
anticipated to bring a chance of precipitation back to portions of
the forecast area late in the week. Mid-range model guidance
remains highly inconsistent with the handling of the low, with
some solutions indicating a weakening of the low pressure system
as it is quickly pulled to the northeast while others indicate the
system failing to be lifted northeast by the jet stream to the
north and instead meandering across the southern Great Plains and
Ozarks region. Which solution materializes will determine the
chances and timing of any precipitation that occurs over Georgia
and will warrant continued monitoring.

.AVIATION...
(00Z TAFS)
Issued at 728 PM EDT Fri Sep 25 2026

VFR conditions will prevail, besides the possibility for BR and
MVFR VIS overnight/early tomorrow (Saturday) morning. Daytime
stratocumulus has largely dissipated and for the most part, only
high-level cloud cover will occur through the TAF period. Winds
will be light/VRB to calm overnight, then become WNW to NNW at
5-10 kts early tomorrow afternoon.

//ATL Confidence...00Z Update...
Medium confidence on potential for MVFR VIS overnight/early
tomorrow morning. High confidence on all other elements.
